PUMP.

Be it known that I, JosnPH Hess, a citizen of the United States, residmg at New Hampton; inthe countyof Chickasaw and State of Iowa, have invented a certain new a and useful. Pump, of which the followingis a specification. I

The object of myinvention is to provide a valve for-pumps and the like of extremely simple, and durable construction.

More particularly it is my ob ect to providea pumpjwith such a valve so constructed and arranged that itmay be readily and easily. taken apart for repa rlng or replacing parts and quickly and easily assembled tor My invention consists-in certain details, in

I the construction, arrangement and combination of-the various parts of the device, whereby the objects contemplated are attained, as hereinafter. more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical, sectional view through a pump cylinder equipped w1th valves embodying my invention. Fig. 2 shows a horizontal, sectional view taken on the line 22 of Fig. 1. Fig. 3 shows a side elevation of a portion of my valve. Fig. 4

shows a perspective view of the movable portion of the valve, and Fig 5 shows a perspective view of one of the rings formed on which are the guide yokes.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally a section of well pipe on the upper end of which is a valve seat 11. The plpe section 10 is connected with the pump cylinder 12 by means of a fitting 13 having the two cylindrical screw threaded portions 14 and 15 which are secured to the pipe 10 and the cylinder 12 respectively, as shown in Fig. 1. The lower portion of my improved valve comprises a ring 16 designed to rest upon the fitting 13 at the lower end of the cylindrical portion 15, and to be, engaged by the lower end of the wall of the cylinder 12.

Near the inner edge of the ring 16, on opposite sides thereof, are upwardly extending guide yokes 17 having substantially the form of an inverted U. The inner portion of the ring 16 is cut away belowone of the guide yokes 17 to form a notch 18, as shown in Fig. 5. i a

The upper end of the cylinder 22 is externally screw threaded to receive the collar 27 having internal screw threads. Above the pump is the piston rod 28 to which is screwed a block 29 having opposite, later of each of which are parallel, downwardly extending arms 31. On the lower ends of each downwardly extending arm 31 is an inwardly extending lug 32.

For the piston, I provide a valve 19 having opposite, laterally extending lugs 20 similar to those of the lower valve.
